nodeJS > TTL > LANC

PostMon Dec 16, 2019 1:08 pm

Hello, does anyone have any idea how to implement the LANC interface in nodeJS?

I have a nodeJS system and a serial TTL adapter with a 2.5mm connector. So far I've found some stuff here in the forum, but without success.

Does anyone know a way to start VideoAssist via LANC with a nodeJS?

There is an older post here in the forum with the id 16676
I used the Delock USB>TTL adapter with the code 83115.

Direct links are available after 10+ posts. ( Anti Robot prevention ) ;)

I dont think a lot of people have experience with Lanc by a usb Serial ttl adapter..

I have done some Lanc in the past and i did not even know it was possible this way. As Lanc is a 2 way protocol on 1 wire. So there need to be some electronics involved to make this happen.

I was going on a very well-founded article.

boehmel . de / lanc . htm

There it is described how similar LANC is to RS232 and there should be a solution. And there are some who have managed it somehow. Therefore now my approach, since I have to start and stop the VideoAssist reliably for a mobile setup.

You can try use this as a starting point, the command format should be the same. https://create.arduino.cc/projecthub/L- ... l-l-70f735
